Paper Abstract

A multi-function optical computing system performing the NOR and NAND operations with two photorefractive BaTiO3 crystals is proposed. Instead of using the interference between the input signals and local incoherent erasing, we use incoherent erasing techniques in the construction of this system. The multi-function system works with different polarization states of the input optical waves. The system works with different polarization states of the input optical waves. The system is able to accept temporally incoherent and spatially incoherent signals. Optical experimental result with spatially incoherent optical images demonstrating the incoherent parallel processing capabilities and the multi-function logic operations of the system are shown.
